MUSIC-BOOK HOLDER AND LEAF-TURNER.

Specification of Letters Patent.

Patented Oct. 10, 1911.

Application filed May 20, 1910. Serial No. 562,474.

To all whom it may concern:

Be it known that we, lVILLIAM H. TRAYER and FRANK CAMPBELL, citizens ofthe United States, residing at Carlisle, in the county of Cumberland andState of Pennsylvania, have invented new and useful Improvements inMusic-Book Holders and Leaf-Turners, of which the following is aspecification.

This invention relates to music book holders and leaf turners of thattype in which a leaf can be turned over and back again as required,the'musician having merely to press upon a button to effect the turningof the leaf.

The invention has for one of its objects to provide an extremely simple,inexpensive and practical device of this character which stably supportsthe music book in open position while the second leaf of the music canbe freely turned and re-turned without requiring the performer to stopplaying.

Another object of the invention is the provision of a novel form ofmusic leaf turning element which consists of members engaging the leafto be turned at its opposite sides adjacent the binding, said membershaving laterally projecting transparentarms which extend horizontallyacross opposite faces of the sheet or leaf at a point intermediate itstop and bottom so that as the element turns, the leaf or sheet will turnwith it.

Another object of the invention is the provision of a novel arrangementof upstanding members on a supporting base or rest which serve to holdthe music book open.

lVith these objects in view and others as will appear as the descriptionproceeds the invention comprises the various novel features ofconstruction and arrangement of parts which will be more fully describedhereinafter and set forth with particularity in the claim appendedhereto.

In the accompanying drawing, which illustrates one embodiment of theinvention :--Figure 1 is a perspective view of the apparatus. Fig. 2 isa plan view thereof showing a music book in position, and one leafthereof at an intermediate position in its turning. Fig. 3 is alongitudinal section of the device showing by dotted lines thebook-holding members folded. Fig. 1 is a central transverse section.Fig. 5 is a detail view of the operating means for the leaf turningelement. Fig. 6 is an enlarged perspective view of a leaf turningelementwith portions broken away.

Similar reference characters are employed to designate correspondingparts throughout the several views.

Referring to the drawing, A designates the base of the apparatus whichmay be a strip of wood to form a support or rest for the music book, theunder surface of the base being provided with transverse strips 1 offelt so that when the apparatus is placed on a music holder of a pianoor organ, it will not scratch or mar the instrument, and also on thebase may be provided spring clips 2, whereby the apparatus can befastened to a music rack. At the center of the base A is a chamber 3extending from the top to the bottom in which is mounted a frame B thatsupports the operating means for the leaf-turning element. This meanscomprises a central vertical shaft 4, which is provided with a pinion orgear 5 that meshes with oppositely disposed rack bars 6 and 7 that slidehorizontally in guides 8 on the frame B, and projecting forwardly fromthe rack bars are stems or rods 9 that pass forwardly through openings10 in the base and on these rods are push but-- tons 12 arranged side byside. When one push button is in the other is out and while the outerone is pushed inwardly, the other moves outwardly. The shaft 4 projectsout of the frame B and has its upper end so constructed as to detachablyconnect with the leaf turning element C. The frame B is held in thechamber of the base by clips 13 secured to the base and projecting underthe frame. On the front edge of the base is a metal piece 14 throughwhich the pushbutton stems extend, and upon removal of this plate andthe clips 13, the frame B can be taken out.

The leaf-turning element C consists of two upwardly extending rods 15which have their lower ends anchored in a base 16 that is in the form ofa ring which fits over the projecting end of the shaft 4- and extendingdiametrically of the ring and secured there to is a key 17 which fits ina slot 18 in the upper end of the shaft 4. It is merely necessary toslip the base member of the leafturning element over the shaft to lockthe element thereon, and the removal of the element is correspondinglyeasy. The upper ends of the rods 15 are bent horizontally to affordconnection with transparent arms 19. These arms may be in the form ofcelluloid or other transparent strips and they are adapted to engage thebody portion of the leaf to be turned, and since they are transparent,they will not conceal any of the notes of the music. The leaf to beturned is inserted between the rods or bars 15 which can be sprung apartin adjusting the leaves thereto and the book will be so supported thatthese rods will be parallel with the binding of the book and as close aspossible thereto. Hence, as the element turns on its own axis, it willcause the leaf to turn through 180. For each apparatus, the leaf-turningelements of different heights will be employed for different size music,it being preferable to have the arms 19 engage the leaf near the middlethereof.

In order to support the book in upright position, a plurality ofupstanding members or supports are provided on the base A. The covers ofthe book are adapted to rest against and extend in front of the upwardly extending members 20 disposed a suitable distance apart atopposite sides of the center of the base and in a line behind theleaf-turning element. The lower ends of these members are disposed insockets 21 in the base and are mounted on horizontal pivots 22 so thatthese members can fold inwardly toward the center in over-lappingrelation so as to take up less room and per mit the device to be foldedfor transportation. The covers and leaves of the books that are not tobe turned are held back by means of short upwardly extending members 23which are pivoted in a socket 2 1: in the base so as to fold flatagainst the latter. These members are short so as not to conceal any ofthe music as they engage the first and fourth pages of the music that isbeing played. These members 23 are set inwardly near the leaf-turningelement, and also forwardly of the rear supporting members 20. Thecentral portion or back of the book is mounted on a central support orrest D which is disposed immediately behind the leaf'turning element.-This support is constructed of a single piece of wire that has its endbent into short upstanding members 24 that engage behind the book andcooperate with the members 20 and 23 to hold the book rigidly in place.The members 24 have horizontal base portions 25 that are connected witha bar portion 26, there being eyes 27 at the ends of the bar forreceiving screws 28 that fasten the device D to the base. Theintermediate portion of the bar 26 is formed into a forwardly extendingcentral tongue 29 which terminates adjacent the base of the leafturningelement, and the bottom edge of the back of the book rests on thistongue. It will thus be obvious from Fig. 2, that two bars or backsupports are provided for the book, namely, the members 20 and 24 andsingle front supports 23. In order to prevent the leaf to be turned fromdragging on the top surface of the base, the latter has arcuate ribs 30,on the bottom of which the leaf rides in the turning movement.

From the foregoing description taken in connection with the accompanyingdrawing, the advantages of the construction and of the method ofoperation will be readily apparent to those skilled in the art to whichthe invention relates, and while we have described the principle ofoperation of the invention, together with the apparatus which we nowconsider to be the best embodiment thereof, we desire to have itunderstood that the apparatus shown is merely illustrative and that suchchanges may be made when desired as are within the scope of the claim.

Vhat we claim as new and desire to secure by Letters Patent is Thecombination of a supporting structure for a book, a leaf turning elementmounted thereon, and means mounted on the structure to operate theelement including a member vertically mounted and slotted at its upperend, said element having abase formed of a ring to detachably fit aroundthe member, a cross key in the ring to engage in the slot of the member,vertical bars anchored at their lower ends in the ring, andleaf-engaging arms on the said bars.

In testimony whereof we affix our signatures in presence of twowitnesses.
